- Boiling Point Definition: The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. Therefore, the boiling point of a liquid depends on atmospheric pressure. The boiling point becomes lower as the external pressure is reduced.

Boiling point The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the surrounding environmental pressure. Thus, the boiling point is dependent on the pressure.he boiling point of a liquid varies depending upon the surrounding environmental pressure. A liquid in a partial vacuum has a lower boiling point than when that liquid is at atmospheric pressure. A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure.

Saturated Vapor Pressure Boiling Point. The boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure. For water, the vapor pressure reaches the standard sea level atmospheric pressure of 760 mmHg at 100°C.rdinary evaporation is a surface phenomenon-since the vapor pressure is low and since the pressure inside the liquid is equal to atmospheric pressure plus the liquid pressure, bubbles of water vapor cannot form.

Boiling Unsourced material may be challenged and removed. (December 2009). Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.

What is the definition of boiling point of a substance in terms of its vapor pressure ? First, the boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. To make it easier to understand, think of atmospheric pressure as the air in the world pushing at a certain person/object. The vapor pressure is the pressure exerted by the gas (evaporated liquid). Now, let’s tackle the definition of boiling point by using real-life examples. We’ll start with water. Water boils at 100 degrees Celsius at an atmospheric pressure of 1 atm (one of the units for pressure).

What is the definition of boiling point of a substance in terms of its vapor pressure ? Best Answer: The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid. A liquid in a vacuum environment has a lower boiling point than when the liquid is at atmospheric pressure.

- Boiling occurs when the vapor pressure reaches or exceeds the surrounding pressure from the atmosphere or whatever else is in contact with the liquid. At standard atmospheric pressure (1 atmosphere = 0.101325 MPa), water boils at approximately 100 degrees Celsius. That is simply another way of saying that the vapor pressure of water at that temperature is 1 atmosphere.

What is the boiling point of water? Water vapour doesn't boil, but liquid water's boiling point is 100 degrees C, or 212 degrees F. boiling point is that point at which the vapour pressure of a liquid become equ … al to the atmospheric pressure at a particular temperature. for example boiling point of water is 100 degree Celsius that is at this temperature vapour pressure of water is equal to the atmospheric pressure so there is no boiling point of water vapour since it is not a liquid and boiling point is only determined ...

Boiling Transition boiling is an intermediate, unstable form of boiling with elements of both types. The boiling point of water is 100 °C or 212 °F but is lower with the decreased atmospheric pressure found at higher altitudes. Boiling water is used as a method of making it potable by killing microbes that may be present.
